Opfindelsen angår en hejsemekanisme til skibe således som nærmere angivet i krav l's indledning.The invention relates to a hoisting mechanism for ships as specified in the preamble of claim 1.

En bøjestation er et apparataggregat, der anvendes ved 5 havforskning, hvori f.eks. måleudstyr til havforskning er fastgjort til kablet eller rebet mellem ankeret og bærebøjen. I den tidligere kendte teknik, f.eks. som kendt fra USA-patentskrifterne nr. 3.074.370 og 3.974.793, nedfires og ophejses nedsænkeligt udstyr ved hjælp af en 10 hjælpeenhed, som sænkes ned over skibssiden ved hjælp af en svingbar bom med tilhørende spil. En sådan indretning er ikke velegnet til at håndtere udstyr, der skal fastgøres til et kabel eller tov med bestemte afstande mellem et anker og en bøje. Dersom en sådan operation udføres 15 med bommen svinget indad, må der ligge lange længder kabel eller tov løst på dækket, og dersom den udføres med bommen svinget udenbords, vil kablet eller tovet svinge i takt med skibets bevægelser, og vil derfor ikke let kunne håndteres sikkert fra dækket. På tilsvarende måde vil, 20 når der anvendes en sædvanlig david, skibets bevægelser bevirke visse problemer, fordi fastgørelsen af udstyret til kablet eller tovet må udføres ud over skibssiden.A bending station is an apparatus used for marine research, in which e.g. measuring equipment for marine research is attached to the cable or rope between the anchor and the carrier. In the prior art, e.g. As known from United States Patent Nos. 3,074,370 and 3,974,793, submersible equipment is lowered and raised by a 10 auxiliary unit, which is lowered over the ship's side by a swivel boom and associated winches. Such a device is not well suited for handling equipment to be attached to a cable or rope at certain distances between an anchor and a buoy. If such an operation is performed with the boom pivoted inward, long lengths of cable or rope must be loosely mounted on the deck, and if it is carried out with the boom pivoted outboard, the cable or rope will pivot in line with the ship's movements and will therefore not be easily handled. safe from the deck. Similarly, when using a conventional david, the movements of the ship will cause certain problems because the attachment of the equipment to the cable or rope must be performed beyond the ship's side.

Derved kan skibets bevægelser forårsage en pendulbevægelse af lasten med hertil knyttede store forskydninger og 25 kræfter. Lasten kan ramme davidens ben eller skibsskroget, hvad der kan medføre beskadigelser på måleudstyret, der kan være yderst kostbart. En svingende last forårsager også fare for folk, som arbejder på dækket.Thereby, the ship's movements can cause a shuttle movement of the cargo with associated large displacements and 25 forces. The cargo can hit David's legs or the ship's hull, which can cause damage to the measuring equipment which can be extremely costly. A swinging load also causes danger to people working on the tire.

Det er opfindelsens formål at anvise udformningen af en 30 hejsemekanisme af den indledningsvis angivne art, der kan anvendes i stedet for davider under undgåelse af de hertil knyttede ulemper og faremomenter, og dette formål opnås ved en mekanisme, som ifølge opfindelsen er ejendommelig ved den i krav l's kendetegnende del angivne 35 udformning og indretning.It is an object of the invention to provide the design of a hoisting mechanism of the type mentioned initially that can be used in place of davids in order to avoid the associated disadvantages and hazards, and this object is achieved by a mechanism which according to the invention is characterized by the The characterizing part of claim 1, the design and the device.

Ved hjælp af mekanismen ifølge opfindelsen opnås et betydeligt bedre herredømme over laster, der skal bevæges udenbords.By means of the mechanism according to the invention a significantly better control over loads to be moved outboard is obtained.

Der sker ingen bevægelse svarende til den pendulbevægelse, der finder sted mellem støttebenene på en sædvanlig david.There is no movement similar to the shuttle movement that takes place between the support legs of a conventional david.

5 Opfindelsen gør det muligt at føre kablet fra skibets hejsespil til den plane vippeplatform på en beskyttet måde, f.eks. gennem dækket eller i render anbragt på dækket. Når vippeplatformen befinder sig i sin øvre stilling, er det også muligt at føre kablet på beskyttet måde til vippeplatformens 10 trisse.The invention makes it possible to route the cable from the ship's hoisting game to the flat tilting platform in a protected manner, e.g. through the deck or in trays placed on the deck. When the rocker platform is in its upper position, it is also possible to guide the cable in a protected manner to the pulley of the rocker platform 10.

Udstyret fastgøres til kablet, mens vippeplatformen befinder sig i den hensigtsmæssige arbejdsstilling i et passende niveau, hvori det udstyr, der skal fastgøres til kablet, hviler på den i denne stilling i hovedsagen vandrette vippe-15 platform. Den del af kablet, der løber ud i havet, er fortrinsvis forbundet med skibet ved hjælp af en bremseindret-ning eller en anden tilsvarende indretning, f.eks. under mellemkomst af vippeplatformen, så at den del af kablet, der befinder sig på vippeplatformen, er spændingsfri.The equipment is attached to the cable while the rocker platform is in the appropriate working position at a suitable level, wherein the equipment to be attached to the cable rests on the horizontal rocker platform in this position. The portion of the cable flowing into the sea is preferably connected to the ship by means of a braking device or other similar device, e.g. during the mediation of the rocker platform so that the part of the cable located on the rocker platform is voltage free.

20 Opfindelsen skal i det følgende forklares nærmere under henvisning til det på tegningen viste udførelseseksempel på en hejsemekanisme ifølge opfindelsen, idet fig. 1 i perspektiv viser mekanismen med vippeplatformen i den vandrette, indad vippede stilling, og 25 fig. 2 på tilsvarende måde som fig. 1 viser mekanismen med vippeplatformen i den udad vippede stilling.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail with reference to the exemplary embodiment of a hoisting mechanism according to the invention shown in the drawing. 1 is a perspective view of the mechanism of the tilting platform in the horizontal, inwardly tilted position; and FIG. 2 in a manner similar to FIG. 1 shows the mechanism of the tilting platform in the outwardly tilted position.

Den på tegningen viste mekanisme består i hovedsagen af en plan vippeplatform 10, som på begge længdekanter er udformet med lodrette sidevægge 11a og 11b. En rulle 13 30 er ved hjælp af akseltappe 15 drejeligt lejret ved den ene endekant af vippeplatformen 10,. og i den modsatte endekant er der drejeligt lejret en trisse 21. Vippeplatformen 10 er forbundet med skibsdækket ved at være 3The mechanism shown in the drawing consists essentially of a flat tilting platform 10, formed on both longitudinal edges with vertical side walls 11a and 11b. A roller 13 30 is rotatably supported by one of the shaft pins 15 at one end edge of the rocker platform 10. and at the opposite end edge there is rotatably mounted a pulley 21. The rocker platform 10 is connected to the ship deck by being 3

vippeligt lejret på lodrette konsoller 14a og 14b, der er fastgjort i den umiddelbare nærhed af skibets yderklædning 23.tiltably mounted on vertical brackets 14a and 14b secured in the immediate vicinity of the outer shell 23 of the ship.

Til kanten af skibets yderklædning 23 er der ved hjælp 5 af svingtappe 18 forbundet to vandrette styr 17, der er indrettet til at styre hejsekablet 20. Styrene 17 er ved hjælp af henvisningstallet 17' vist i sin udad svingede styrestilling, i hvilken kablet 20 løber i mellemrummet V mellem dem.At the edge of the outer casing 23 of the ship, two horizontal guides 17 are arranged by means of pivot pin 18 arranged to control the hoisting cable 20. The guides 17 are shown by their reference numeral 17 'in their outwardly pivoted guide position in which the cable 20 runs. in the space V between them.

10 Platformen 10 kan vippes enten ved håndkraft eller ved hjælp af dertil indrettede påvirkningsorganer, f.eks. en hydraulisk cylinder, og vippeplatformen 10 kan fastlåses i den i fig. 1 viste arbejdsstilling i en passende højde H fra dækket. I denne arbejdsstilling kan f.eks. et apparat K, 15 der er antydet i afbrudt streg i fig. 1, løftes op på vippeplatformen .10. Apparatet K fastgøres til kablet 20 f.eks. ved hjælp af et sjækkel 22 eller andre organer, idet kablet 20 over trissen 21 på vippeplatformen 10 strækker sig hen til skibets ikke viste hejsespil gennem 20 dækket og/eller i render på dækket.The platform 10 can be tilted either by hand or by means of actuating means, e.g. a hydraulic cylinder and the rocker platform 10 can be locked in the position shown in FIG. 1 at an appropriate height H from the tire. In this posture, e.g. an apparatus K, 15 indicated in broken line in FIG. 1, is lifted onto the rocker platform .10. The apparatus K is attached to the cable 20 e.g. by means of a shackle 22 or other means, the cable 20 over the pulley 21 of the rocker platform 10 extending to the hoisting winch of the ship not shown through the deck and / or in the grooves on the deck.

På den ende af vippeplatformen 10, der ligger nærmest styrerullen 13, er der fastgjort en bremseindretning 19, der f.eks. består af to overfor hinanden anbragte bremse-klodser, idet kablet 20 er således anbragt, at det stræk-25 ker sig gennem mellemrummet mellem dem. Ved at bevæge brem-seklodserne imod hinanden ved hjælp af et passende,ikke vist påvirkningsorgan er det muligt at fastlåse hejsekablet 20 ved mellemkomst af vippeplatformen 10 i forhold til skibet, så at det stykke af kablet 20, der er anbragt på 30 vippeplatformen 10, er spændingsfrit.At the end of the rocker platform 10 which is closest to the guide roller 13, a braking device 19 is mounted, which e.g. consists of two opposite brake pads, the cable 20 being arranged so that it extends through the space between them. By moving the brake pads against one another by means of an appropriate actuator, not shown, it is possible to lock the hoist cable 20 by means of the rocker platform 10 relative to the ship, so that the piece of cable 20 arranged on the rocker platform 10, is voltage-free.

Efter at apparatet K ved hjælp af et sjækkel 22 eller et hertil svarende organ er blevet fastgjort til hejsekablet 20" i den i fig. 1 viste stilling, vippes vippeplatformenAfter the apparatus K has been secured to the hoisting cable 20 "in the position shown in Fig. 1 by means of a shackle 22 or a corresponding means, the tilting platform is tilted

Derved kommer vippeplatformen 10' til at strække sig ud fra skibets yderklædning 23, d.v.s. ud over havet, i en 5 afstand L. Under ned- eller ophejsning løber hejsekablet 20 styret af trissen 21 på vippeplatformen 10' og af en anden trisse 24 til skibets hejsespil. I den i fig. 2 viste stilling kan apparatet K eller et hvilket som helst andet, tilsvarende apparat eller instrument ved hjælp af 10 hejsekablet 20 eller et hertil svarende reb sænkes ned i havet og på lignende måde løftes op af havet.Thereby, the rocker platform 10 'extends from the outer shell 23 of the ship, i.e. beyond the sea, at a distance of 5 L. During down or lifting, the hoist cable 20 is guided by the pulley 21 on the rocker platform 10 'and by another pulley 24 for the ship's hoisting game. In the embodiment shown in FIG. 2, the apparatus K or any other corresponding apparatus or instrument may be lowered into the sea by means of the hoisting cable 20 or a corresponding rope and similarly lifted by the sea.

Vippeplatformen 10' er indrettet til at holdes i den i fig. 2 viste stilling ved hjælp af et dertil egnet begrænsningsorgan eller en hvilken som helst anden hertil svarende 15 indretning. Når forskelligt udstyr skal løftes op fra havet i den i fig. 2 viste stilling af vippeplatformen 10', løftes udstyret først til niveauet for vippeplatformen 10, som derpå vippes til den i fig. 1 viste stilling, hvorved udstyret -i det viste eksempel apparatet K - der er løftet op fra ha-20 vet, kan anbringes på vippeplatformen 10 under dennes styrede bevægelse til den vandrette stilling/ hvori de fornødne operationer kan udføres og apparatet K om nødvendigt aftages fra kablet 20", og eventuelt efter yderligere fornødne operationer igen sænkes ned i havet.The rocker platform 10 'is adapted to be held in the position shown in FIG. 2 by means of a suitable limiting means or any other device corresponding thereto. When different equipment is to be lifted from the sea in the one shown in fig. 2, the equipment is first raised to the level of the rocker platform 10, which is then tilted to the position shown in FIG. 1, whereby the equipment - in the example shown the apparatus K - lifted from the spring can be placed on the rocker platform 10 during its controlled movement to the horizontal position / in which the necessary operations can be carried out and the apparatus K removed if necessary. from the cable 20 ", and if necessary after further necessary operations are lowered again into the sea.

25 I det stadium, hvorunder apparatet løftes i havet, kan styrene 17 svinges omkring deres svingtappe 18 til stillingen 17' eller til en passende vinkel i mellemrummet ved, så at kablet 20 styres på en passende måde til forbindelse med vippeplatformen 10. Ved hjælp af styrene 17 sikres det også, at 30 kablet 20 styres mellem bremseklodserne i bremseindretningen 19. Dersom bremseindretningen er af en sådan art, at kablet 20 kan bringes i forbindelse med den på anden måde, er styrene 17 ikke tvingende nødvendige.At the stage during which the apparatus is lifted into the sea, the guides 17 can be pivoted about their pivot pin 18 to the position 17 'or to a suitable angle in the space, so that the cable 20 is guided in an appropriate manner for connection to the rocker platform 10. the guides 17 are also ensured that the cable 20 is guided between the brake pads in the brake device 19. If the brake device is of such a nature that the cable 20 can be connected to it in another way, the guides 17 are not imperative.
